Zinc Plus Selenium 90 Capsules

Zinc Glycinate Chelate with Selenium and Copper for Immune, Antioxidant, and Thyroid Support

Dr. Mercola Zinc Plus Selenium delivers zinc as zinc glycinate chelate — an amino acid-chelated form where zinc is bound to the amino acid glycine for enhanced absorption and intestinal tolerance — alongside selenium and copper in a formula designed for comprehensive mineral immune support. Zinc glycinate chelate has superior bioavailability compared to zinc oxide (the cheapest and most poorly absorbed form used in many supplements) and provides zinc in a form that is gentle on the stomach and less likely to cause the nausea occasionally associated with zinc sulfate or zinc gluconate supplementation.

Zinc is involved in over 300 enzymatic reactions throughout the body and is essential for virtually every aspect of immune function: T-cell development and thymic function, NK-cell activity, neutrophil function, cytokine signaling, and antibody production. Selenium is an essential cofactor for the glutathione peroxidase enzyme system — the body's primary intracellular antioxidant defense — and for the selenoprotein deiodinase enzymes required for T4-to-T3 thyroid hormone conversion. Copper is included specifically to maintain the healthy zinc-to-copper ratio that long-term zinc supplementation requires, as sustained zinc intake without copper can deplete copper status and impair copper-dependent enzymes including superoxide dismutase (SOD) and ceruloplasmin.
